 Panhandles later this evening.

.SHORT TERM...
(This evening through Monday night)
Issued at 1237 PM CDT Sun Oct 5 2025

Latest 18Z observations across the southern Plains continues to
show a trailing cold front associated from a low in the upper
midwest will slowly sweep through the Panhandles later this
afternoon into the evening hours. Some of the more agressive
12-15Z hi-res/CAM model and numerical data does show portions of
the north central and northeastern Panhandles with ML/MU CAPE
approaching 1000J/kg along with effective shear increasing into
the early evening hours with an SSW H850 LLJ increasing. Our
caveat for any widespread precipitation could be the initial cap
ahead of the main front. Not a large one, but with more limited
shear before sunset and the LLJ present, showers and thunderstorm
coverage will be more limited (less than 20% across the
Panhandles), before increasing rain chances for the NE Panhandles
to near 30% after sunset. NBM probs > 0.25" between now and
sunrise tomorrow morning gives some locations along the front
where storms can develop a 10-20%R chance of seeing said rainfall
amounts, but this coverage is rather limited. Some storms
furthest north could be severe with damaging wind gusts and large
hail, especially with the best lift for storms along the
progressing cold front. Thunderstorm activity will wane past
midnight for the majority of the area as the airmass becomes more
stable in the wake of the front.

In the wake of the cold front, the H700 CAA will leisurely move
south into the Panhandles. Went a few clicks below the NBM 25th
percentile for high temperatures tomorrow as cloud cover increases
and rain chances return along the slow moving cold front. High
temperatures tomorrow will range from the mid 60s in the NW
Panhandles well behind the front to mid 80s in the far SE TX
Panhandle where they will still likely be ahead of the front most
of the day tomorrow.

.LONG TERM...
(Tuesday through next Saturday)
Issued at 1237 PM CDT Sun Oct 5 2025

Starting off on Tuesday with NBM 25th percentile high temperatures
once again where cloud cover and rain chances will keep the
Panhandles about 10 to 15 degrees below average for early October
with high temperatures ranging from the lower 60s to lower 70s
across the entire region. Latest 05/12Z model and numerical
guidance shows a low amplitude H500 ridge slowly building
northward throughout the remainder of the week, with high
temperatures slowly climbing back to and slightly exceeding
average highs by the end of the week. There is little accord with
rain chances from the latest global guidance. Depending the
wavelength and where the apex of the sinusoidal curve sets up,
with westerly flow aloft, we could see some ridge rollers bring
some rain chances or large scale subsidence under the ridge could
keep us dry as well. Will watch trends closely getting further
into the week.

.AVIATION...
(00Z TAFS)
Issued at 421 PM CDT Sun Oct 5 2025

A cumulus field is currently building over the central panhandles.
This field will be the source of the rain showers and
thunderstorms during this afternoon and evening. In the northern
panhandles the arrival of the cold front will allow for a low
chance of strong to severe thunderstorms. The main threat from
these such storms will be large hail and damaging downburst winds.
For today KGUY and KAMA have a high enough chance for the rain
showers and thunderstorms to be reflected within the TAFs. KDHT
still has a chance to see these but the odds are just to low to be
reflected within the TAF. Overnight there is a very low chance for
continued rain showers, the odds of these impacting any terminal
are too low to be reflected within the TAFs. Winds shifting
sharply from the south to the north can be expected with the
passage of the cold front at all terminals during the overnight
hours. For Monday afternoon further rain showers and thunderstorms
have a low to moderate chance of forming in the panhandles. For
this TAF period KAMA has high enough chances of these impacting
the terminal to be reflected within the current TAF. for KDHT and
KGUY the rain and thunderstorms will most likely begin just after
the end of the current TAFs. A strong to even severe thunderstorm
cannot be fully ruled out during Monday`s afternoon and evening.
Further during this round of rain showers and thunderstorms a deck
of low clouds has a moderate chance of forming at least in the
northern panhandles with MVFR conditions. KGUY is the station most
likely to see this bank of low cloud initially.
